Q1. Two resistance are given as 𝑅1 = ( 10 ± 0 . 5 ) Ω and 𝑅2 = ( 15 ± 0 . 5 ) Ω . The percentage error in the measurement of equivalent resistance when they are connected in parallel is (1) 6 . 33 (2) 2 . 33 (3) 5 . 33 (4) 4 . 33
What This Question Tests
This question tests the ability to calculate equivalent resistance for parallel combination and propagate errors to find the percentage error in the equivalent resistance.
Concepts Tested
Formulas Used
1/R_eq = 1/R1 + 1/R2
ΔR_eq/R_eq² = ΔR1/R1² + ΔR2/R2²
Percentage Error = (ΔR_eq/R_eq) * 100
